From boot camp to the Iraqi desert, best friends Collin, Max, and Gavin have been through hell and back. But these rugged Marines might need help facing their biggest challenge: raising Collin's nine-month-old daughter, Chloe.

After the death of his girlfriend in an accident, Collin Montgomery has sworn off serious relationships. His buddies have his back-and convince him it's okay to cut loose sometimes. Enter the hottest, smartest girl he's ever met. But what he really needs is a nanny.
Addison Booker needs a job desperately-and fast. She shows up to interview for the nanny position only to find the sexy, cocky man she can't get out of her head. Collin knows hiring her is a bad idea-they disagree about almost everything-but Addison is so good with little Chloe. And there's no substitute for chemistry, right?
